It depends on what type of movies you prefer.Italy had a great "B production" back in the 70s or 80s. They are slasher movies that have a very niche audience, but they still have sort of a cult following.Also... Asian movies! Asian horror movies are really good. In fact Hollywood loves those movies so much they end up making so many remakes of famous Asian horror movies.

I agree with you with Asian horror movies are really good. Japanese horror films are f****d up, I'll leave a link in here for you to take a look:

I saw this movie "Shutter" (2004 - from Thailand, not 2008 version) and it is reaaaaaaally good!. "Ringu" and "Ju-On" are the originals for "The ring" and "The grudge", both are better in their original versions. I've not been able to watch any other because I'm not prepared to xD.
